Maybe we should start copying from the manual. So here we go:
The DIST function creates an array in which each array element value is
proportional to its frequency. This array may be used for a variety of
purposes, including frequency-domain filtering.
This routine is written in the IDL language. Its source code can be found in
the file dist.pro in the lib subdirectory of the IDL distribution.
(I would post the code too, but it is copyrighted, so you will have to look
at RSI\IDLxx\lib\dist.pro yourself. Sorry for the inconvenience)
